I explore how and and to what extent policy uncertainty can account for the observed long-run cross-country differences in capital price and levels of aggregate investment and output. I present a model economy where the industry-level policy-related investment cost is uncertain. Holding the...

This article aims to analyze the Feldstein-Horioka hypothesis, which suggests a strong correlation between investments and savings in advanced economies. Additionally, the analysis of the eldstein-Horioka hypothesis was expanded to include emerging markets and developing economies in order to...

Digitalisation may be viewed as a sequence of supply and technology shocks affecting the economy through productivity and output, employment and labour markets, competition and market structure. This paper focuses on the effects of digitalisation on economic growth, and how those effects may...

This paper reviews empirical research on the impact of government capital spending on economic growth. The pros and cons of five different ways to model the relationship between public investment and economic growth are reviewed, while some estimation results are presented for illustrative...

We quantify the impact of barriers to international investment, using a novel multi-country dynamic general equilibrium model with heterogeneous investors and imperfect capital mobility. Our model yields a gravity equation for bilateral foreign asset positions. We estimate this gravity equation...

Entrepreneurship, growth and total factor productivity are larger when there is a financial bubble. We explain these facts using a growth model with financial bubbles in which individuals face heterogeneous wages and returns on productive investment. The heterogeneity in the return of investment...
